Police said the friends were at the 12-year-old boy's home Friday night when an argument took place and his 13-year-old friend left. The 12-year-old followed him outside to the 3000 block of Worthington Avenue.

The victim told police the 12-year-old was armed with two kitchen knives that he was swinging erratically. He said he punched the 12-year-old and blocked several knife strikes before suffering a cut to his head. The wound required stitches, according to police.

The 12-year-old was arrested on suspicion of second-degree reckless endangerment and battery.
